Application 1ed January 5, 1914. Serial No. 810,360.`

Be it known that I, REINHOLD KRUMMING, a citizenof the United States, `residing at Milwaukee, Wisconsin, have invented certain new and` useful Improvements 'in Scoring or Crimping Machines for Sheets or Leaves, -of which the following is a specificatin. j

iThis invention Vrelates to in scoring or vcrimping( machines for Sheets o1` leaves;

' Sheets or leaves used for record books are commonly of quite heavy stiff paper. `When such sheets are used in temporary bindersor loose leaf holders ofg certainNwell-known types, the'slieets do not, owing to the manthel following specification.v ,is clearly defined and pointed out in .the

`the binders, lie

\ stiff" character.

lner in which they are bound onretained in flat yunless `some special pro-` vision ismade for hinging or flexing1 portions in the sheets adjacent their binding margin. Further, this ,objection of not ly-` ing flat is sometimes found in permanently bound books Vhaving sheets o f this heavy The objects of my crimping or scoring sheets or leaves to pro- -1 duce'hing'e or flexing portions therein` adjacent their binding margins'. Secondyto provide an improved printing machinel attachment which scores or `crimps sheets or `leaves to produce suitable fleXing or hinging 'portions therein" during the printing ofv the sheets. Third, to provide an improved meansfor attachment having theseadvan-y tages, which is simple'` and I economical'in structure, and very easy to operate. Y

Further objects,"V and objects relatingto i 40'vstructur'al details, will definitely appear from the detailed descripti'on'to follow.

y I accomplish the objects of my'inventionby the devices andmeans described Hin The invention claims.

A "structure which isA a preferred embodi` ment of my invention is clearlyillustrated in the accompanying drawing form'i'ng-k a partof this specification, in which:

`Referring to 'fthe drawing, 1-represents the frame of a cylinder printinginachine and 2 oneflof its cylinders. vThese parts are shownf-in conventional form only.

The crimping or scoring rollers 3 are problades. These rollers 3 are carried by arms'ec having journals projecting to one side from their inner ends. 4The 'ar-ms for longitudinal'adjustment ron the rodq. This rod 6 is supported by the brackets l7 at theside of the cylinder Q, the brackets beingv Vm'ounted on the frameby means of'bolts 8.

The `arms 4 are secured in their.adjustedpo sitions on the rod by means of the collars 9 rovided with setscrews 1 0,`t`here being collarat each side of'each arm. 'See Fig. I. The arms project outwardly `at v11 .beyond the rods and are provided with laterally pro- /je'ctin'g portions 12 with which the adjustf 'scew's are arranged through the bar let arranged 'o 'nthe brackets 7 parallel with the screws] 13` engage. -4These adjustingrodf. The screws 13 are provided withlock nuts 15 and lwith holes 16 adapted toreceive an adjusting tool. These set screws-holdthe printing cylinder with` Arranged on the'l 1 rcylinder oppositefl the rol-ls is. a series of yresilient pads 17. The', pads between each'lgroup of; scores,fas shownv in` 'Fig'.-=III, iny whichthe sheet 18-has `two groups of scores 19, there being anunscored;

4 are mounted to accomplish the pun 100 A 17 fare arranged on` the-cylinder in la l spaced relation sothat there is an unscore ics `portion QObetWeen'thegroups and between :the edgeofthe'sheet'sland the scores. The

sheet is scored von both.sides,-as shownfin y' Fig.'IV,the scoring onopposite sides vbeing` .i alternated. 1` This is accomplished-by. setting the rollers in the desired position to produce the scores on one side when the sheet is printed on that side and then setting crimping rollers over so that when the sheet is printed on the other side it is scored on that side, the scorings coming between those formed previously, as stated.

By printing, I contemplate the headings and not in ordinary practice the ruling of the sheet, as the sheets are preferably ruled before printing the headings and forming the flexible hinge or flexing portions. By this means I produce a sheet which has a \f*ery flexible hinge or flexing portion and at the same time, one which is not likely to break in use or be torn in handling, and the sheets are very economical to produce.

In Figs. V and VI, l show my improvements adapted to a bed or platen machine in which the crimping o-r scoring knives 2l are locked up in a form, as 22, with the type 23 which is indicated in a conventional manner. The blades or knives 21 are arranged side by side, preferably with removable leads or slugs 24 at the sides thereof, so that the slugs may be removedor shifted to set over the knives when it is desired to print and score the sheets on the opposite sides. The quoins 25 are shown in conventional form.

F rom the foregoing, it will be obvious that my improvements are capable of embodiment in various relations to meet the particular requirement. I have illustrated and described my improvements in detail in a simple embodiment and have not attempted to illustrate all the modifications I contemplate as I believe the disclosure made will enable those skilled in the art to embody my improvements as circumstances may dictate. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
